Definitions
- the object of the invention is to provide a method for crack repair on concrete sleepers of track systems, with time-consuming work such as the removal of the track, the track bed and the concrete sleeper can be avoided and a reliable complete crack filling is possible.
- filler one-component, two-component or multi-component epoxy resin or polyurethane.
- the optimum fillers can be selected, put together and used. This improves the quality of the process and the subsequent remediation.
- the respective cracks are rinsed by means of a solvent, the initial conditions in terms of moisture, the type of pre-pollution and the degree of contamination can be positively influenced, and completely eliminate.
- the filler to be used receives optimum application possibilities and bonding possibilities to the concrete material of the concrete sleeper.
- the crack is blown out.
- residues from the solvent used or other residues can be removed.
- the quality of the restoration and the reliability of the backfilling are improved.
- the injection device is used at the free surface by means of filler neck in the crack or placed on the crack by means of rubber lip.
- optimal backfilling or injections of the filling material are achieved.
- the quality of the process is improved.
- the filling is carried out even with continuous or unsteady mechanical stress of the monolithic material.
- the backfilling or rehabilitation of concrete sleepers are possible even in short traffic breaks between trains. Elaborate blockages can be avoided. As a result, a not to be underestimated cost advantage is achieved.
- the concrete threshold in the region of the crack or the crack is mechanically expanded. This simplifies the filling process and makes it more reliable.
- an individual sealing of the lower threshold region takes place with continuous cracking by means of a rapidly dripping material by a lateral introduction. This ensures that the cracks are closed in the lower part of the threshold and thus the subsequently introduced backfill can not escape down from the threshold.
- the rehabilitation of cracks 1 on concrete sleepers 6 represents a high cost factor for the operators of track systems.
- a crack remediation is possible, with the concrete sleeper 6 to be rehabilitated remaining in the track system during the renovation.
- the renovation takes place in successive steps after a detailed crack analysis.
- the crack is first blown out and rinsed with a solvent which, for example, is hydrophobic.
- the crack 1 or the cracks 1 are blown out again.
- the damming 2 takes place here based on the crack analysis.
- the damming 2 is applied to the crack 1 so that this is completely covered.
- the damming 2 is applied in strips along the crack 1 on the crack 1, wherein the damming 2 is made removable at intervals.
- the crack is covered, for example, across the crack course and superimposed by the damming 2.
- 2 open spaces 3 are made at the designated places by removing the damming. If necessary, at this point of the process on the open spaces 3 again a purging and rinsing of the crack 1 or the cracks. 1
- the filler 4 is injected into the crack 1 by means of a per se known injection device and a low-pressure pump.
- a per se known injection device and a low-pressure pump.
- packers ie filler neck
- an optimal Verhell310 is achieved.
- the low-pressure pump is controlled so that the filling material 4 can penetrate into the crack 1 without bubbles.
- the backfilling is monitored by monitoring the escape of the filling material 4 from the crack 1. Based on the monitoring result, the low-pressure pump is controlled.
- the filling is carried out without interruption as a single operation, whereby, taking into account the dripping time of the respective filling material 4, the filling process can be delayed.
- filler 4 is both an epoxy resin and polyurethane in question. Especially with the use of polyurethane rinsing of the crack 1 with a hydrophobic solvent such as acetone is necessary to avoid the consequences of the unfavorable interaction of the polyurethane with water, whereby the necessary stability would not be achieved.
- a hydrophobic solvent such as acetone
- filler 4 allows filling even with continuous or unsteady mechanical stress on the concrete sleeper 6.
- a mechanical extension of the crack 1 or the area is provided directly at the crack. This special care is required to avoid further damage to the concrete sleeper 6.
- the filler neck 5 and the rubber lips 5 can be set so that an escape of the filler 4 will be avoided directly at the filling point.
- a rapidly dripping material is introduced laterally in this area by means of an injector.
- This material is a jelly-like, fast-dripping material, which is adjusted according to humidity, dew point and building temperature. After curing of this material, the fourth step is carried out according to claim 1.
